My sister recently gave me a leather sofa she has had for about 10 years. I am allergic to dogs, and she has a large golder retreiver, but since it was leather, I did not think I would have a problem. I have vacuumed it and cleaned it a couple times, but still after 2 weeks, I am having some pretty severe allergic reactions when I am on the couch. I am starting to think I am allergic to leather. Has anyone heard of a leather allergy?? Do you think it is still just dander on the couch from her dog??
